Abstract:
Belief rule-based (BRB) systems are an extension of traditional IF-THEN rule based systems and capable of capturing complicated nonlinear causal relationships between antecedent attributes and consequents. In a BRB system, various types of information with uncertainties can be represented using belief structures, and a belief rule is designed with belief degrees embedded in its possible consequents. For a set of inputs to antecedent attributes, inference in a BRB system is implemented using the evidential reasoning (ER) approach. In this talk, I will first discuss the inference patterns of BRB systems, including evidential reasoning, multi-model decomposition and distributed approximation. I will then present three different real-world case studies to illustrate its capability of modelling uncertain nonlinear systems.
